Flow pattern of a WLM solution around a microfluidic cylinder

This video depicts the motion of a specific worm-like micellar solution with a cylinder obstructing the flow path. The streak lines are visualized under a microscope using fluorescent tracer particles. As the flow rate of the material increases, the motion of the fluid becomes unstable upstream of the cylinder. This is contrary to the downstream instabilities seen in Newtonian fluids.

To Buckle or Not to Buckle

Testing the stability of cylindrical tube made from 15,360 hexagonally packed magnetic balls (192 rings, each made up of 80 balls). A high-speed camera recording reveals crumpling at the base of the cylindrical tube, reminiscent of paper-like crumpling, when it loses stability from shaking.

The mechanophore glows more intensely as the stretching increases.

The polymer material is stretched with an increasing force resulting in a corresponding brighter emission of light from the mechanophore (here under UV light and with false colors). The graph shows the intensity of the emitted light following punctual increases in the stretching force applied to the polymer.

OIST Study Uncovers Neural Roots of Parkinson's Disease

OIST scientists have gained new insight into the abnormal brain activity underlying Parkinson’s disease. In a mouse model of the disease, the scientists observed that one group of neurons in a particular brain region--the striatum–fire in sync and dominate the overall activity of that region. When striatal neurons are stimulated continuously, they exhibit this abnormal behavior. By stimulating the neurons in precise pulses, the researchers observed that the neurons returned to their normal activity pattern, with groups of cells firing in turn.
